Slavery archaeology update Map from 1830s aids research, excavation

With the help of an early-19th-century insurance map, archaeologists are having an easier time than usual in excavating an important historical site near Montpelier.

The researchers, including 17 students from James Madison University, are unearthing the South Yard, a residential complex where President James Madison's domestic slaves lived and worked.

The insurance map, which came to light in 2002, is proving invaluable.
